Fig. 2. Sensitivity of medial octavolateralis nucleus (MON) units to running water.
Change in discharge rate is plotted as a function of flow velocity. A rate
change of zero indicates that discharge rates in still and running water were
identical. (A) Data from flow-sensitive units that responded with increasing
ongoing discharge rates to increasing flow velocities. Broken lines represent
data from units in which discharge rates decreased at flow velocities above
approx. 10 cm s-1. (B) Data from flow-sensitive units that
responded with decreasing discharge rates to increasing flow velocities. (C)
Data from flow-insensitive units. In these units, ongoing discharge rate in
still water was not different from the ongoing rates measured at any of the
tested flow velocities.
